Strange story, but here it goes.
About a year ago I bought 2 RF P3's 12's Dual RMS 2Ω 600w each. Wired them to a RF Prime R-500-1 RMS 500w @ 2Ω . Thats 250w each less then half then RMS.
Everything runs fine for a year. Fast forward to this week, I decide to change out the amp and get a RF Prime R-1000-D RMS 1000w @2Ω. Still well under the RMS by 100w's each.
Warrant swap, so now both Amps are brand new.
The problem is that the R-500-1 amp is much louder then the new R-1000-D one. If the R-1000-D get anywhere close to sound the R-500-1 puts out, it cuts out completely and cuts back on in cycles.
I changed nothing about the system settings, or wiring setup 2awg power and Neg.
Any Ideas??
